The Society of Thoracic Surgeons General Thoracic Surgery Database: 2021 Update on Outcomes and Research

The Society of Thoracic Surgeons General Thoracic Surgery Database: 2024 Update on Outcomes and Research

The Society of Thoracic Surgeons General Thoracic Surgery Database (STS GTSD) remains the largest and most comprehensive audited thoracic surgical database in the world. As the STS GTSD grows to nearly 1 million cases, the pulmonary resection for cancer and esophagectomy short-term risk models have been refined to provide participants with benchmarked performance reports to facilitate quality improvement efforts. New for 2025 will be the development of long-term risk models and the online release of both short- and long-term risk calculators. A voluntary module to collect neoadjuvant targeted and immunotherapy data has been created and accepted by participants and is rapidly accruing data. STS GTSD participant public reporting has increased 50% over the last 2 years after the application of the U.S. News & World Report 3% transparency credit. All GTSD data analyses are now performed internally by the STS Research and Analytic Center, resulting in multiple publications through the Access & Publication, Task Force on Funded Research and Participant User File mechanisms. Future initiatives include the incorporation of patient-reported outcomes into the STS GTSD, revision of the data collection form to incorporate variables associated with long-term outcomes, and focused efforts to increase the value of STS GTSD participation. This report delineates volume trends, recent initiatives, and the prolific research output emanating from the STS GTSD, reflecting a year of substantial progress and academic productivity.

Preoperative risk-factors for secondary spontaneous pneumothorax surgery in Japan: a nationwide database study

PURPOSE

We aimed to identify preoperative risk factors for secondary spontaneous pneumothorax surgery.

METHODS

The National Clinical Database of Japan, with six annual datasets from 2014 to 2019, was used. All patients who underwent surgery for secondary spontaneous pneumothorax were included, excluding those < 15 years old and those with incomplete data. The effects of preoperative risk factors were analyzed for operative mortality (mortality during hospitalization or within 30 days, regardless of hospitalization status), 30-day mortality, and postoperative respiratory morbidities.

RESULTS

Of the 18,309 patients enrolled in the study, operative mortality, 30-day mortality, and postoperative respiratory morbidities were observed in 654 (3.6%), 343 (1.9%), and 2258 (12.3%) patients, respectively. Increasing age, male sex, body mass index < 18.5 or > 30, performance status > 2, emergent surgery, interstitial pneumonia, and diabetes in preoperative co-morbidity, tumors, and other diseases in underlying lung disease were significant risk factors for operative mortality. Those for 30-day mortality included autoimmune disease instead of male sex and diabetes, while those for postoperative respiratory morbidities included lymphangiomyomatosis instead of a body mass index > 30.

CONCLUSION

We identified many preoperative risk factors for operative mortality, 30-day mortality, and postoperative respiratory morbidities in secondary spontaneous pneumothorax surgery. These findings will assist in selecting appropriate surgical candidates.

Trends and comparative outcomes between operative approaches for segmentectomy in lung cancer

BACKGROUND

Segmentectomy is increasingly performed for non-small cell lung cancer. However, comparative outcomes data among open, robotic-assisted, and video-assisted thoracoscopic approaches are limited.

METHODS

A retrospective cohort study of non-small cell lung cancer segmentectomy cases (2013-2021) from the Society of Thoracic Surgeons General Thoracic Surgery Database was performed. Baseline characteristics were balanced using inverse probability of treatment weighting and compared by operative approach. Volume trends, outcomes, and nodal upstaging were assessed.

RESULTS

Of 9927 patients who underwent segmentectomy, 84.8% underwent minimally invasive surgery, with robotic-assisted thoracoscopic surgery becoming the most common approach in 2019. Open segmentectomy is more likely to be performed at low-volume centers (P < .0001), whereas robotic-assisted thoracoscopic surgery is more likely to be performed at high-volume centers (P < .0001). Video-assisted thoracoscopic surgery had a higher open conversion rate than robotic-assisted thoracoscopic surgery (odds ratio, 11.8; CI, 7.01-21.6; P < .001). Minimally invasive surgery had less 30-day morbidity compared with open segmentectomy (video-assisted thoracoscopic surgery odds ratio, 0.71; 95% CI, 0.55-0.94; P = .013; robotic-assisted thoracoscopic surgery odds ratio, 0.59; CI, 0.43-0.81; P = .001). The number of nodes and stations harvested were highest for robotic-assisted thoracoscopic surgery; however, N1 upstaging was more likely in open compared with robotic-assisted thoracoscopic surgery (odds ratio, 0.63; CI, 0.45-0.89; P < .007) and video-assisted thoracoscopic surgery (odds ratio, 0.61; CI, 0.46-0.83; P = .001).

CONCLUSIONS

Segmentectomy volume has increased considerably, with robotic-assisted thoracoscopic surgery becoming the most common approach. Minimally invasive surgery has less major morbidity compared with open segmentectomy, with no difference between video-assisted thoracoscopic surgery and robotic-assisted thoracoscopic surgery. However, risk of open conversion is higher with video-assisted thoracoscopic surgery. Robotic-assisted thoracoscopic surgery had increased nodal harvest, whereas hilar nodal upstaging was highest with thoracotomy. This study reveals significant differences in outcomes exist between segmentectomy operative approach; the impact of approach on survival merits further investigation.

Preoperative Chest CT Myosteatosis Indicates Worse Postoperative Survival in Stage 0-IIB Non-Small Cell Lung Cancer

Background Skeletal muscle density (SMD) and intermuscular adipose tissue (IMAT) are myosteatosis markers. The prognostic value of myosteatosis markers in preoperative risk stratification of patients with early-stage non-small cell lung cancer (NSCLC) remains unknown. Purpose To assess whether increased myosteatosis markers at chest CT before lung resection of early-stage NSCLC are associated with and predictive of worse overall survival (OS). Materials and Methods This retrospective cohort study included patients with stage 0-IIB NSCLC who underwent lobectomy or bilobectomy at three hospitals between 2014 and 2017. The indexes (cross-sectional area [in centimeters squared] divided by height [in meters squared]) and densities (mean attenuation [in Hounsfield units]) of skeletal muscle, subcutaneous adipose tissue (SAT), and IMAT were assessed at CT at the level of the 12th thoracic vertebral body via semiautomated threshold-based segmentation. Associations of SMD and the IMAT index with OS were evaluated via separate Cox proportional hazards models adjusted for skeletal muscle index, SAT index, SAT density, and relevant confounders. The ability of indexes and densities to predict OS was explored with penalized Cox proportional hazards models and internally validated concordance statistics. Results Among 838 patients (median age, 68 years [IQR, 61-74 years]; 475 [56.7%] female patients), 219 died after a median follow-up of 5.3 years (IQR, 3.0-6.4 years). Increased myosteatosis, represented by decreased SMD and an increased IMAT index, was associated with worse OS (adjusted hazard ratio, 0.87 [95% CI: 0.80, 0.93]; P < .001 and adjusted hazard ratio, 1.24 [95% CI: 1.12, 1.37]; P < .001, respectively). There was no evidence of an association between OS and skeletal muscle index, SAT index, and SAT density. The predictive performance (concordance) increased from 0.723 (95% CI: 0.686, 0.753) to 0.731 (95% CI: 0.692, 0.762) after including myosteatosis markers. Conclusion Increased thoracic myosteatosis markers were associated with worse OS after lobectomy or bilobectomy of stage 0-IIB NSCLC, independent of skeletal muscle index, SAT index, and SAT density, and improved OS prediction. © RSNA, 2025 Supplemental material is available for this article.

The risk analysis index is an independent predictor of outcomes after lung cancer resection

BACKGROUND

The Risk Analysis Index (RAI) is a frailty assessment tool based on an accumulation of deficits model. We mapped RAI to data from the Society of Thoracic Surgeons (STS) Database to determine whether RAI correlates with postoperative outcomes following lung cancer resection.

METHODOLOGY/PRINCIPAL FINDINGS

This was a national database retrospective observational study based on data from the STS Database. Study patients underwent surgery 2018 to 2020. RAI was divided into four increasing risk categories. The associations between RAI and each of postoperative complications and administrative outcomes were examined using logistic regression models. We also compared the performance of RAI to established risk indices (American Society of Anesthesiology (ASA) and Charlson Comorbidity Index (CCI)) using areas under the Receiver Operating Characteristic (ROC) curves (AUC). Results: Of 29,420 candidate patients identified in the STS Database, RAI could be calculated for 22,848 (78%). Almost all outcome categories exhibited a progressive increase in marginal probability as RAI increased. On multivariable analyses, RAI was significantly associated with an incremental pattern with almost all outcomes. ROC analyses for RAI demonstrated "good" AUC values for mortality (0.785; 0.748) and discharge location (0.791), but only "fair" values for all other outcome categories (0.618 to 0.690). RAI performed similarly to ASA and CCI in terms of AUC score categories.

CONCLUSIONS/SIGNIFICANCE

RAI is associated with clinical and administrative outcomes following lung cancer resection. However, its overall accuracy as a surgical risk predictor is only moderate and similar to ASA and CCI. We do not recommend routine use of RAI for assessment of individual patient risk for major lung resection.

Quality improvement mechanisms to improve lymph node staging for lung cancer: Trends from a statewide database

OBJECTIVE

Our statewide thoracic quality collaborative has implemented multiple quality improvement initiatives to improve lung cancer nodal staging. We subsequently implemented a value-based reimbursement initiative to further incentivize quality improvement. We compare the impact of these programs to steer future quality improvement initiatives.

METHODS

Since 2016, our collaborative focused on improving lymph node staging for lung cancer by leveraging unblinded, hospital-level metrics and collaborative feedback. In 2021, a value-based reimbursement initiative was implemented with statewide yearly benchmark rates for (1) preoperative mediastinal staging for ≥T2N0 lung cancer, and (2) sampling ≥5 lymph node stations. Participating surgeons would receive additional reimbursement if either benchmark was met. We reviewed patients from January 2015 to March 2023 at the 21 participating hospitals to determine the differential effects on quality improvement.

RESULTS

We analyzed 6228 patients. In 2015, 212 (39%) patients had ≥5 nodal stations sampled, and 99 (51%) patients had appropriate preoperative mediastinal staging. During 2016 to 2020, this increased to 2253 (62%) patients and 739 (56%) patients, respectively. After 2020, 1602 (77%) patients had ≥5 nodal stations sampled, and 403 (73%) patients had appropriate preoperative mediastinal staging. Interrupted time-series analysis demonstrated significant increases in adequate nodal sampling and mediastinal staging before value-based reimbursement. Afterward, preoperative mediastinal staging rates briefly dropped but significantly increased while nodal sampling did not change.

CONCLUSIONS

Collaborative quality improvement made significant progress before value-based reimbursement, which reinforces the effectiveness of leveraging unblinded data to a collaborative group of thoracic surgeons. Value-based reimbursement may still play a role within a quality collaborative to maintain infrastructure and incentivize participation.

Overall survival in low-comorbidity patients with stage I non-small cell lung cancer who chose stereotactic body radiotherapy compared to surgery

OBJECTIVE

To evaluate trends in the utilization of stereotactic body radiotherapy (SBRT) and to compare overall survival (OS) of patients with early-stage non-small cell lung cancer (NSCLC) undergoing SBRT versus those undergoing surgery.

METHODS

The National Cancer Database was queried for patients without documented comorbidities who underwent surgical resection (lobectomy, segmentectomy, or wedge resection) or SBRT for clinical stage I NSCLC between 2012 and 2018. Peritreatment mortality and 5-year OS were compared among propensity score-matched cohorts.

RESULTS

A total of 30,658 patients were identified, including 24,729 (80.7%) who underwent surgery and 5929 (19.3%) treated with SBRT. Between 2012 and 2018, the proportion of patients receiving SBRT increased from 15.9% to 26.0% (P < .001). The 30-day mortality and 90-day mortality were higher among patients undergoing surgical resection versus those receiving SBRT (1.7% vs 0.3%, P < .001; 2.8% vs 1.7%, P < .001). In propensity score-matched patients, OS favored SBRT for the first several months, but this was reversed before 1 year and significantly favored surgical management in the long term (5-year OS, 71.0% vs 41.8%; P < .001). The propensity score-matched analysis was repeated to include only SBRT patients who had documented refusal of a recommended surgery, which again demonstrated superior 5-year OS with surgical management (71.4% vs 55.9%; P < .001).

CONCLUSIONS

SBRT is being increasingly used to treat early-stage lung cancer in low-comorbidity patients. However, for patients who may be candidates for either treatment, the long-term OS favors surgical management.

Public Health Informatics and the Perioperative Physician: Looking to the Future

The role of informatics in public health has increased over the past few decades, and the coronavirus disease 2019 (COVID-19) pandemic has underscored the critical importance of aggregated, multicenter, high-quality, near-real-time data to inform decision-making by physicians, hospital systems, and governments. Given the impact of the pandemic on perioperative and critical care services (eg, elective procedure delays; information sharing related to interventions in critically ill patients; regional bed-management under crisis conditions), anesthesiologists must recognize and advocate for improved informatic frameworks in their local environments. Most anesthesiologists receive little formal training in public health informatics (PHI) during clinical residency or through continuing medical education. The COVID-19 pandemic demonstrated that this knowledge gap represents a missed opportunity for our specialty to participate in informatics-related, public health-oriented clinical care and policy decision-making. This article briefly outlines the background of PHI, its relevance to perioperative care, and conceives intersections with PHI that could evolve over the next quarter century.

Quality and Impact of Manuscripts Using The Society of Thoracic Surgeons National Databases

BACKGROUND

The Society of Thoracic Surgeons (STS) National Databases contain the largest and most comprehensive cardiac, thoracic, and congenital surgery data available. In this analysis characteristics of manuscripts that used the STS National Databases were examined to evaluate the quality and impact of these publications.

METHODS

Manuscripts published from 2010 to 2020 that used the STS National Databases (Adult Cardiac, General Thoracic, and Congenital Heart Surgery) were examined. The number of times cited per published manuscript, journal of publication, and journal CiteScore were assessed. Author characteristics, including institutional association and h-index, were evaluated for first and last authors.

RESULTS

Of 539 published manuscripts, 179 (33.2%) used the Adult Cardiac Surgery, 128 (23.7%) the Congenital Heart Surgery, 85 (15.8%) the General Thoracic Surgery, and 136 (25.2%) used unspecified STS National Databases. Collectively the analyzed manuscripts were cited 18,943 times, with a mean of 35.1 (range, 0-528) citations per manuscript. Manuscripts were published in 97 journals with a mean year-adjusted CiteScore of 5.6 (range, 0.1-60.2). Authors associated with 361 institutions contributed to published manuscripts. The mean h-index of first authors was 24.6 (range, 0-100) and of last authors was 44.1 (range, 0-164). From 2010 to 2020 first authors wrote a mean of 1.6 (range, 1-31) and last authors wrote a mean of 1.9 (range, 1-29) STS National Databases publications.

CONCLUSIONS

The STS National Databases are some of the most robust data collection sources available to cardiothoracic surgeons. These data have enabled valuable research in respected journals from authors of varying experience levels.

Evolving Perspectives on Esophagectomy Care: Clinical Update

Recent changes in perioperative care have led to new perspectives and important advances that have helped to improve outcomes among patients treated with esophagectomy for esophageal cancer.

Epidemiology of Postoperative Complications After Esophagectomy: Implications for Management

BACKGROUND

Despite advances in operative techniques and postoperative care, esophagectomy remains a morbid operation. Leveraging complication epidemiology and the correlation of these complications may improve rescue and refine early recovery pathways.

METHODS

This study retrospectively reviewed all esophagectomies performed at a tertiary academic center from 2014 to 2021 and quantified the timing of the most common complications. Daily incidence values for index complications were calculated, and a covariance matrix was created to examine the correlation of the complications with each other. Study investigators performed a Cox proportional hazards analysis to clarify the association between early diagnosis of postoperative atrial fibrillation and pneumonia with subsequent anastomotic leak.

RESULTS

The study analyzed 621 esophagectomies, with 580 (93.4%) cervical anastomoses and 474 (76%) patients experiencing complications. A total of 159 (25.6%) patients had postoperative atrial fibrillation, and 155 (25.0%) had an anastomotic leak. The median (interquartile range [IQR]) postoperative day of these complications was day 2 (IQR, days 2-3) and day 8 (IQR, days 7-11), respectively. Our covariance matrix found significant associations in the variance of the most common postoperative complications, including pneumonia, atrial fibrillation, anastomotic leak, and readmissions. Early postoperative atrial fibrillation (hazard ratio, 8.1; 95% CI, 5.65-11.65) and postoperative pneumonia (hazard ratio, 3.8; 95% CI, 1.98-7.38) were associated with anastomotic leak.

CONCLUSIONS

Maintaining a high index of suspicion for early postoperative complications is crucial for rescuing patients after esophagectomy. Early postoperative pneumonia and atrial fibrillation may be sentinel complications for an anastomotic leak, and their occurrence may be used to prompt further clinical investigation. Early recovery protocols should consider the development of early complications into postoperative feeding and imaging algorithms.

A decade of surgical outcomes in a structured lung cancer screening program

OBJECTIVE

Lung cancer screening can decrease mortality. The majority of screen-detected cancers are early stage and undergo surgical resection. However, there are little data regarding the outcomes of surgical treatment outside of clinical trials. The purpose of this study was to compare the outcomes of curative resection for screen-detected lung cancers with nonscreened, incidentally detected cancers at an institution with a structured screening program.

METHODS

Patients undergoing lung cancer curative resection from January 2012 to June 2021 were identified from a prospective database. Baseline patient characteristics, tumor characteristics, and outcomes were compared between cancer detected from screening and cancer detected incidentally.

RESULTS

There were 199 patients in the incidental group and 82 patients in the screened group. Mean follow-up was 33.3 ± 25 months. The screened group had more African Americans (P = .04), a higher incidence of emphysema (P = .02), less prior cancers (P < .01), and more pack-years smoked (P < .01). The screened group had a smaller size (1.74 vs 2.31 cm, P < .01); however, pathologic stage was similar, with the majority being stage I. Postoperative morbidity, 30-day mortality, and overall and recurrence-free survival were similar between groups. Only 48.7% of the incidental group met current US Preventative Services Task Force screening criteria (age 50-80 years, ≥20 pack-year smoking history).

CONCLUSIONS

Screen-detected lung cancers have excellent postoperative and long-term outcomes with curative resection, similar to incidentally detected cancers. A large portion of incidentally detected lung cancers do not meet current screening guidelines, which is an opportunity for further refinement of eligibility.

Immediate Postoperative High Syndecan-1 is Associated with Short-Term Morbidity and Mortality After Robot-Assisted Esophagectomy: A Prospective Observational Study

BACKGROUND

Disruption of the endothelial glycocalyx (EG) is associated with a poor prognosis in various clinical settings. This study aimed to determine the association between immediate postoperative serum syndecan-1 levels, a representative marker for EG degradation, and major postoperative morbidity and mortality in patients undergoing robot-assisted esophagectomy.

METHODS

Patients who underwent robot-assisted esophagectomy between 2018 and 2022 were prospectively enrolled. The primary outcome was the association between immediate postoperative syndecan-1 levels and the occurrence of major postoperative morbidity and mortality within 30 days of surgery. Patients were classified into low and high syndecan-1 groups based on the optimal cut-off value of syndecan-1 for predicting major morbidity and mortality. A multivariable logistic regression analysis was performed to investigate the risk factors for major morbidity and mortality.

RESULTS

A total of 207 patients were analyzed. Patients with high syndecan-1 levels (≥48 ng/mL) showed a significantly greater incidence of unexpected returns to the operating room and anastomotic leaks and longer durations of hospital and intensive care unit stays than patients with low syndecan-1 levels (<48 ng/mL). Immediate postoperative syndecan-1 levels ≥48 ng/mL (odds ratio [OR] 2.32, 95% confidence interval [CI] 1.23-4.76), American Society of Anesthesiologists physical status ≥III (OR 3.36, 95% CI 1.56-7.22), and current smoker (OR 4.02, 95% CI 1.52-10.61) were independently associated with major morbidity and mortality within 30 days of esophagectomy.

CONCLUSIONS

Immediate postoperative syndecan-1 levels ≥48 ng/mL could be used for the early detection of patients at high risk of complications after robot-assisted esophagectomy.

This document is an update of the multidisciplinary document HEMOMAS, published in 2016 with the endorsement of the Spanish Scientific Societies of Anaesthesiology (SEDAR), Intensive Care (SEMICYUC) and Thrombosis and Haemostasis (SETH). The aim of this document was to review and update existing recommendations on the management of massive haemorrhage. The methodology of the update was based on several elements of the ADAPTE method by searching and adapting guidelines published in the specific field of massive bleeding since 2014, plus a literature search performed in PubMed and EMBASE from January 2014 to June 2021. Based on the review of 9 guidelines and 207 selected articles, the 47 recommendations in the original article were reviewed, maintaining, deleting, or modifying each of them and the accompanying grades of recommendation and evidence. Following a consensus process, the final wording of the article and the resulting 41 recommendations were approved by all authors.

The Increasing Adoption of Minimally Invasive Lobectomy in the United States

BACKGROUND

The objective of this study is to evaluate the trends of and outcomes associated with the use of minimally invasive lobectomy for stage I and II non-small cell lung cancer (NSCLC) in the United States.

METHODS

The use of and outcomes associated with open and minimally invasive lobectomy for clinical stage I and stage II NSCLC from 2010 to 2017 in the National Cancer Database were assessed by multivariable logistic regression and propensity score matching.

RESULTS

From 2010 to 2017, use of minimally invasive lobectomies increased for stage I NSCLC (multivariable-adjusted odds ratio [aOR] 4.52; 95% CI, 3.95-5.18; P < .001) and stage II NSCLC (aOR 4.38; 95% CI, 3.38-5.68; P < .001). In 2015, for the first time, more lobectomies for stage I NSCLC were performed by minimally invasive techniques (52.2%, n = 5647) than by thoracotomy (47.8%, n = 5164); and in 2017, more lobectomies for stage II NSCLC were performed by minimally invasive techniques (54.7%, n = 1620) than by thoracotomy (45.3%, n = 1,342). From 2010 to 2017, the conversion rates from minimally invasive to open lobectomy for stage I NSCLC decreased from 19.6% (n = 466) to 7.2% (n = 521; aOR 0.32; 95% CI, 0.23-0.43; P < .001). Similarly, from 2010 to 2017, the conversion rates from minimally invasive to open lobectomy for stage II NSCLC decreased from 20% (n = 114) to 11.5% (n = 186; aOR 0.39; 95% CI, 0.21-0.72; P = .002).

CONCLUSIONS

In the United States, for stage I and stage II NSCLC from 2010 to 2017, the use of minimally invasive lobectomy significantly increased while the conversion rate significantly decreased. By 2017, the minimally invasive approach had become the predominant approach for both stage I and stage II NSCLC.
